TL;DR
A mound system is an elevated septic drainfield built from engineered sand fill above the native grade, used where shallow groundwater, bedrock, or slow soils rule out conventional trenches. A pump chamber doses effluent up into the sand bed in timed cycles, where it is treated before reaching the limiting layer below.
What it means
A mound system is an elevated septic drainfield built from engineered sand fill above the native grade, used where shallow groundwater, bedrock, or slow soils rule out conventional trenches. A pump chamber doses effluent up into the sand bed in timed cycles, where it is treated before reaching the limiting layer below. The visible berm, the pump, and the engineering make it one of the costlier residential systems, with electrical and pump maintenance as ongoing obligations.
